RECOMMENDATION
Staff recommends that the City Council approve Amendment No. 4 to the City’s professional engineering services contract with Burns & McDonnell Engineering Company, Inc. (BMcD) for W.O. 19-42: West End Water Treatment Plant Project in the amount of $347,957.
BACKGROUND (Consistency with Adopted Plans and Policies, if applicable)
When using a General Contractor/Construction Manager (GC/CM) type delivery method, an initial contract is put in place and then contract amendments are used to add scope when the details of the design become known as the project progresses. To date, there have been three contract amendments for this project. There will be additional amendments as the project moves from the design and bidding into the construction.
In August 2019, City Council approved an $883,732 contract with BMcD for the preliminary design of the West End Water Treatment Plant (WEWTP). In April of 2021, Council approved $3,778,342 contract Amendment No. 1 to complete the final design of the WEWTP and the transmission main to connect the WEWTP to the distribution system. Amendment No. 2 for $69,278 was approved by Council in August 2021 to complete the final design of the Hesper Road gravity sewer extension and the final design of a sewer lift station and force main to serve the WEWTP. Council approved Amendment No. 3 for $306,720 in February 2023 for additional survey and geotechnical work, value engineering, Hesper sewer bidding services, rate escalation and membrane filter procurement and submittal review.
Amendment No. 4 would add the following scope of work totaling $347,957:
· Relocate the plant to the western portion of the City's property in order to reduce the cost of future raw water transmission main construction and to minimize impact to wetlands identified by the U.S. Army Corps of Engineers (USACE). Design changes include new and/or revised site civil, yard piping, hydraulic modeling, permitting, and sanitary sewer lift station and force main.
· Coordinate with the General Contractor/Construction Manager (GC/CM) through February 2024. Previous amendments provided for these services through January 2023; however, additional redesign, estimating and bidding efforts were required for value-engineering the project design.
· Bidding phase services for the Zone 3 water line.
